1、unit 1 dream home(b)课前导入 基数词和序数词对于已学过的基数词和序数词，你记得多少呢？我们来检测一下吧！ 知识梳理 1. id like to live next to a restaurant.（1）“id like to”是“i would like to”的缩写，would意为“想”，是情态动词，常与like连用。在英语中“would like”是一个常用的结构，意为“想，愿意”，用来表示主语的意愿。“ .”意为“想要某物/做某事”，表示“想要做某事”时，可以和“sb. want to do sth. ”替换，但是“would you like.”的语气要更加的委婉。

2、例如he would like some fruit.他想要一些水果。 id like to have a rest.我想要休息一下。我想要和你交朋友。 （2） “想要某人做某事”例如：id like you to meet my parents. 我想要你见见我父母。 你想要他帮你女儿学英语吗？ （3）这样的句式变成一般疑问句时，把would提前，意为“想要做吗？”；变成否定句时，在would的后面加not，意为“不想做”。例如：would you like to show me your new camera? 你愿意把你的新照相机给我看看吗？ 我不想去电影院。 2. i always h

3、ave fun with my dog there.fun为不可数名词，意为“娱乐，乐趣”，可用much；lots of；a lot of等修饰。 意为“玩得高兴，有趣”，相当于 或 ，其后接可接“ 或 ”。例如：我们和他一起聊天，玩得很高兴。 他玩电脑游戏很开心。 【拓展】fun的形容词为 ，意为“有趣的，可笑的”。例如：他经常给我讲许多有趣的故事。 3. can you ask him to call me back?（1） “让某人做某事”，其否定形式为 “让某人不要做某事”。例如：我经常让他帮助我做家务。 妈妈让我不要在太阳下看书。 （2） ask sb. sth. “问某事某事”；“

4、ask for sth.”意为“请求某事，要某物”，相当于“want sth.”。例如：我能问你一些问题吗？ 如果你有问题，请寻求帮助。 （3） “向某人要某物”。例如：如果你找不到去学校的路，请找警察帮忙。 4. i would like to invite my friends to watch films with me at the weekend.本句中的invite是及物动词，意为“邀请”，常用于下列结构：（1） 邀请某人 例如：你邀请北京的朋友了吗？ （2） 邀请某人去某地 例如：为什么不邀请他们来我们学校？ （3） 邀请某人吃饭 例如：李林经常邀请我吃饭。 （4） . 邀请某人

5、做某事 例如：我们邀请我们的父母来参加聚会。 grammar1. 基数词和序数词请自己总结；将总结出来的知识点罗列在下列方框中。语法数词的用法概念引入数词是指表示数目多少或顺序先后的词。表示数目多少的数词叫基数词，如 one, five, ten, thirty, sixty-five 等；表示顺序先后的数词叫序数词，如 first, sixth, tenth, twenty-first 等。数词用法相当于名词和形容词，在句中可用作主语、宾语、表语、定语、同位语等。 用法讲解（一）、基数词。1. 基数词的写法或读法。（1）对于20以内的基本的数字，需要同学们牢记。要注意其中的一些规律。例如：1

6、0-20的数字都是“-teen”结尾等。（2）十位数与个位数之间要加连字符。例如：23twenty-three（3）百位数与个位数之间要加and。例如：201 two hundred and one 642 six hundred and forty-two拓展：除此之外，较大的数字是将数字由右向左每三位加一个逗号，使一个数字分成几个小节，第一个逗号前用thousand（千），第二个逗号前用million（百万），第三个逗号前用billion（十亿），然后依次读出（写出）例如：68,343 sixty-eight thousand, three hundred and forty-three

7、13, 526, 300 thirteen million, five hundred and twenty-six thousand, three hundred注意：英语中没有“万”和“亿”这两个单位，只有“百万（million）”和“十亿（billion）”；因此“一万”是用10个千，也就是“ten thousand”来表示的，“一亿”是用“one hundred million”来表示的。2. 基数词的用法（1）表示确切数目时，hundred，thousand和million只能用单数，不能变复数；但表示不确定的数目时，要用复数形式，并且要加上of。例如：five hundred 五百

8、 three thousand 三千 hundreds of 成百上千的 thousands of 成千上万的 millions of 数百万的（2）基数词可以用来表示时间。例如：7:30 seven thirty / half past seven 6:45 six forty-five / a quarter to seven 8:00 eight oclock（3）基数词可以用来表示年代。例如：1980年，读作nineteen eighty 2020年，读作two thousand and five（4）基数词可以用来表示事物的编号。例如：第209房间 room 209 第三部分 sec

9、tion 3/part 3 南京路308号 308 nanjing road 电话号码398688 tel 3698688（5）基数词可以用于某些数学算式。例如：3+2=5 three and two is five。 （三加二等于五） 10-5=5 ten minus five is five。 （十减五等于五）（6）基数词可以用来表示年龄。例如：she is five years old. 她五岁了。 in his twenties 在他二十几岁时（二）、序数词1. 基数词变序数词的方法。（1）序数词是由基数词在词尾加th构成，表示顺序的数词。它的前面一般要用定冠词the。例如：the s

10、ixth 第六。（2）序数词的1，2，3这三个数字是特殊变化，即它们不是在基数词的后面加th，需要特别记忆和掌握。第一是：first，第二是：second，第三是：third。（3）从第四到第十九的序数词都是在基数词的后面加th，但要注意：第五是fifth，第八是eighth，第九是ninth，第十二是twelfth这几个特殊变化。（4）整十位的序数词是其相对应的基数词把字母y改为ie再加th。例如：twentytwentieth第二十，fortyfortieth第四十。（5）从二十一到九十九的序数词，前面的十位数用基数词，后面的个位数用序数词，中间用连字符号连接。例如：twenty-four

11、twenty-fourth第二十四。（6） 第一百、第一千、第一百万分别在相对应的基数词的后面直接加th。即：hundredth，thousandth，millionth。拓展：序数词的缩写形式。序数词的缩写形式由阿拉伯数字加上序数词的最后两个字母构成.前三个数字时,特殊情况,分别是:first1stsecond2nd third3rd 以后的均是在最后的数字后加“-th”即可。例如：forth4th twenty-first21st ninety-fifth95th 2. 序数词的用法。（1）序数词的前面一般要用定冠词the表示第几的意思。例如：you are the second one

12、to know the way. 你是第二个知道方法的人。（2）表示编号的时候，经常把基数词放在名词的前面表示顺序，相当于the序数词名词。例如：lesson fivethe fifth lesson 第五课。（3）表示分数的时候，分子用基数词，分母用序数词，当分子大于1的时候，分母用复数形式即：在th的后面加字母s。例如：2/5 two fifths。（4）序数词在名词的前面经常作定语修饰名词，但是当名词的前面已经有了物主代词的时候，序数词的前面不再用定冠词the。例如：this is my third question. 这是我的第三个问题。（5）序数词可以表示日期。例如：march 18

13、th, 1978 （1978年3月18日）注意：数词的用法除了以上讲到的基数词和序数词的用法之外，还有小数的用法，倍数的表达法等，我们会在以后的学习中逐渐学到。2. 基数词和序数词你至今都学过哪些？典例讲解. 句型转换，每空一词。1. the kfc is on the sixth floor.
